a sexual act that requires 3 people. 2 guys, one chick, and 1 other unfortunate soul. The chick bends over and one guy takes her from behind, while the other puts it in her mouth and then the two guys give a high ten, giving the illusion of the Eiffel Tower. The unfortunate soul is there to take the picture. No one will believe you if you don't have the proof.

An act in which three or more people encircle another group of one or more people by clasping each other's hands above their heads, and proceed to exclaim "EIFFEL TOWER, BITCHESSS!" before scattering. The origins (and raison d'etre) of the act are unknown, but it is supposed that the name refers to the shape of the joined arms of the encirclers.
